Title: Elastic and plastic damper
Inventor: SODA ISANARI
IPC: F16F1/36
Filed: 1989-12-11
Abstract: PURPOSE:To promote the effect of vibration control by forming an elastic and plastic body having a U-shaped part, a guide wheel mounted on the U-shaped part of the elastic and plastic body and bearing members to which a leg section of the elastic and plastic body is fixed. CONSTITUTION:An elastic and plastic damper is constituted of U-shaped members 1 to function as an elastic and plastic body, a guide wheel 2 with which a U-shaped part is interlocked, bearing members 3 and wires 4 to bear the wheel 2 on the bearing members 3. After that, when a relative variation in the bearing members 3 occurs in the direction of the arrow, the members 1 move to a part to generate strain or a part to release strain as the rotation of the wheel 2, and the whole form is changed from U to J. Then, curvature is constrained by the wheel 2, and the concentration of strain to a specific section is avoided. According to the constitution, the effect of vibration control against the large external disturbance can be also promoted.

IPC: C03C15/00
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of efflourescent matter of soda glass products, etc., or to remove the formed efflourescent matter. SOLUTION: Transparent glass sheet caps 1 and 1 (30 pieces) formed from soda glass sheets are housed into a corrugated fiber board box 2 and 3 cc vinegar (3% acetic acid) is sprayed to the inside walls of this corrugated fiber board box 2. The corrugated fiber board box is then hermetically sealed. The transparent glass sheet caps 1 are taken out of the corrugated fiber board box 2 by opening the box after storage for one month and are inspected. The result is the complete absence of the formation of the efflourescent matter. The formation of the efflourescent matter is entirely nil when the transparent glass sheet caps 1 are rested as they are in the air. As an another example, the surfaces formed with the transparent glass sheet caps are wiped (1 to 3 times) with cloth impregnated with the vinegar (3% acetic acid), by which the efflourescent matter is entirely wiped away.  The formation of the efflourescent matter is entirely nil when the transparent glass sheet caps removed of the efflourescent matter and rested for one month.

CONSTITUTION:In the case of a flaw on the disk 1, a preformat signal S31a and a tracking error signal S32a are both fluctuated. In the case of an external impact, the signal 32a is generated as an error amt. When the flaw is found on the disk 1 by comparing of comparators 61 and 62, a 1st deciding signal S60a of the disk 1 is outputted by a flaw/impact deciding circuit 60 of a drop- out detection processing part 50, and when the external impact is found, a 2nd deciding signal S60b of the disk 1 is outputted. When the signal 60a is outputted, a tracking error signal S32a-1 at a low level is outputted from a gain variable circuit 70, and is given to a servo control part 42. On the other hand, when the signal S60b is outputted, the signal S32a-1 at a high level is outputted from the circuit 70, and is given to the control part 42.

Title: Cement solidification of cinder ash of radioactive waste
Inventor: HARASHINA HEIHACHI
IPC: G21F9/30
Filed: 1989-12-12
Abstract: PURPOSE:To intend shortening of a time required for cement solidification by putting the cinder ash of radioactive wastes and a water-setting cement into a container and by rotating the container rapidly. CONSTITUTION:Water and cinder ash are put into a container A and mixed together, and then a water-setting cement such as a silica cement or aluminous cement, and an appropriate amount of fine aggregate, if required, are also put in and are roughly kneaded together and sealed completely. Then, the container A is placed on a turntable 1, is covered by a thermally insulated case 2, is fastened and is rotated very rapidly, and consequently a centrifugal force is given to contained mixture objects to put them in a compressed condition, and hydration reaction of the cement is urged by heat generated by the compression and the hydration reaction of the cement. Also, a hardened part of the cement having comparatively large specific weight, gathers to positions peripheral to an outside of the container A and therefore hardening begins from the outside part, and the part is apt to be embodied with the container A. Thus, fluid substances which mainly gather at a central part, show tendency of retarded rotation and temperature to rotational direction is uniformed, and therefore a time required for solidification can be much shortened.

Abstract: PURPOSE:To enhance the durability of photoconductive toner by using selected wavelengths which have been obtained from white light which passed through wavelength selecting filters in order to carry out exposure with the use of the wavelengths which are most preferable for the photoconductive toner. CONSTITUTION:White light from a light source 21 which is not a specific wavelength light source such as LEDs or the like but which is a white light source is led through filters 4Y,... for selecting wavelengths most suitable for photoconductive toner. Then, light having selected wavelengths which have passed through the filters 4Y,... is used for exposure. In this case, these filters may not only be incorporated integrally with the exposure systems but also be provided independently therefrom. With this arrangement, it is possible to select arbitrary wavelengths from the white light, thereby it is possible to carry out exposure and development with the use of light having wavelengths suitably corresponding to color toners.
